Question.....

Q: Does every believer have to be able to speak in "Tongues"?

A: Apparently NOT....Listen to the Pen of Paul under Inspiration in 1 Corinthians

For to one is given by the Spirit the word of wisdom; 

to another the word of knowledge by the same Spirit; 

To another faith by the same Spirit;

to another the gifts of healing by the same Spirit; 

To another the working of miracles; 

to another prophecy; 

to another discerning of spirits; 

to another divers kinds of tongues; 

to another the interpretation of tongues: 

But all these worketh that one and the selfsame Spirit, dividing to every man severally as He will.
1 Corinthians 12:8-11
